Carey was spotted enjoying sushi at Nobu in Malibu with Bryan Tanaka, the guy who got so flirty with her that her fiancee, Australian billionaire James Packer, confronted him in her dressing room and had him banned from Caesar’s Palace in Las Vegas, where Carey performs.

Carey and Packer reportedly broke up earlier this week. Reports varied as to why, with one theory having something to do with Packer doing something “terrible” to her assistant on a yacht last month in Greece.

TMZ reported that back in June, Tanaka was injured, but still showed up to one of Carey’s shows. Packer thought that was strange, and ended up confronting Tanaka. A source told the website there was lots of yelling, but it wasn’t clear if things got physical.

You have to be careful with those Australian guys. They all carry really big knives and wrestle alligators.

Packer then used his casino ties to ban Tanaka from Caesar’s Palace. Which Carey reportedly didn’t have a big issue with, because he was injured and couldn’t dance anyway. Plus, according to TMZ, she was frightened off Packer, who she thinks is “mentally unstable.”
